There is an old tale... It is said that a palace of pearls lies at the bottom of the ocean. There, in the Otohime's paradise, an ancient law is passed down. According to legend, there is an ark that must never be opened.
Time passes until the dawn of the Palsifal dynasty. As an era of peace and calm ends, trouble is brewing in the ocean's depths. After a chance meeting with a turtle, Aldo gets caught up in the turbulence. As if swallowed up in the vortex of the thousand-year old-ark.
Black Pearls are rewarded from sparkle points in Dragon Palace (Very Hard). Each sparkle point is guaranteed to yield 1 Black Pearl, and a single Very Hard run can have anywhere from 1 to 3 sparkle points. The number of sparkle points available in the current run corresponds to the number of turtles seen at its entrance.
Once you completed the episode go to the east part of Dragon Palace - Inner Wall (present) and you'll notice a lot of Ammonites blocking the way.
Enter the room nearby to find a portal hidden behind some sort of wall decoration. Go to Dragon Palace past and get rid of the Ammonite and the coral. Enter the Storage (the room at the end) and open the chest to find a Fish Stone.
If you go back to the present Dragon Palace and enter the storage again you'll find the Thief Walrath. Defeat it to earn the award "Consumed with the Sand at Kira Beach"
First, visit a house in Dragon Palace - Outer Wall Bamboo containing a pair of fishfolk twins (bottom middle of map). Tap on the bookcase to read a journal entry that will tell you about a secret stash and a clue on to how to locate it (it tells of a marked pillar).
The pillar (which is marked with an 'X') is in Dragon Palace - Outer Wall Plum, in the bottom left corner.
Go to Dragon Palace Past - Outer Wall Pine (in the past, not present time). Enter a house towards the middle (it contained an upside down squid in the present time) and tap on the bookshelf to reveal a small tunnel area. You will find a memo. Note: You will have to progress to Chapter 3 first (just keep following the quest marker, you'll eventually pass by that house).
Finally, go back to the same house in present time (i.e. Dragon Palace - Outer Wall Pine), unlock the tunnel area, and tap on the middle rock to obtain Crafted Armor.
